ELECTRIC CALL-CLOCK.

Application filed April l To aZZ whom it may concern:

Be it known that I, OWEN P. RAGAN, a citizenfof the Unit-ed States, residing at Ridgeway, in the county of Harrison and State of h/Iissourh/have invented a new and useful Improvement in JElectric @aV-Cloche,

pecication.

`This invention designed primarily for a call'cloclr for hotel use, also he used in any fplace where an electric alarm may be used where the alarm is 'to e given at some predetermined time. It is designed tering any one, any number or all of the bells connected with it at any time the operator maydesire to set it for..

It consists in a 'circuit closing clock through which the circuits are automatic ally closed d't the designated time and a switchboard through which the various circuits are connected to the clock in such a manner as to close the circuits -art the desired time. .f

In the accompanying drawings: A"Figure l -is a diagrammatic side elevation, parts being-removed' and the frontof a casing being. partly broken away. Fig. 2 is a ver- .tical4 section through the casing. Fie'. 3

2:: -1savvert1cal section through the dial plate of a lclock. Figs.v fl, 5 and 6 are detaillside cldvations of portions of certa-in dial rings.

In these drawings l represents theiace of a clock provided with an hour hand? and aiminute-hand 3. A sectional ring d formed of twelve metal segments insulated from eachother is carried by the face. of the clock, which face is also 'of a non-con duc'tino` material, and .the hour hand travels ,upon the ring 4. Concentric with said ring is a second ring, oi larger diameter formed of six insulated sections An outer conn centric ring 6 is of greater height than the.

rings 4 and 5, and is notchcdor cut away at intervals as shown at 7 and 7a. The notches at 7a areof greater length than those at 7, and come opposite meeting end portions of the segments 5, each notch 7a overlapping end portions of two of the segments The notches are formed with a perpendicular wall at one end, and with an inclined wall at the opposite end; the last mentioned wall being the one approached by the minute 'hand as it travels clockwise. The rin-g G therefore may he described as a metalring having a'plurality ci' cams :3 spaced apart,

the spaces varying in length.ov

might result in lifting the hour hand frornf' the circle during a part of a revolution, thus breaking the circuit, or it might cause excessive friction between the hand and the ring of conducting material. To `prevent such action, the hour hand 2 is formed in sections hinged together, and a spring 9 is secured to the inner section and bears uponthe outer face of the hinged outer section, thus holding it to the rin 4 at all times and also allowing itto llft should the arbor not be perfectly true and there should be at any point a tendency for the hand to bind. The minute hand is also formed in two sections, but in order to prevent any interference lbetween the two hands the minute hand is spaced a considerable distance from the .hour hand and its outer hinged section is angled as shown at l0 in order to.. carry itin to the outer margin of the dial face. A spring .11 is fixed to the inner portion bears upon the outer hinged portion. This spring not only' serves the same purpose as the spring l0 but also serves an additional purpose inasmuch as the minute hand travels over both the segmental ring 5 land the ring 6. As lng as the minute hand is moving along one' of the cams 8 it is lifted out of contact with the ring 5 but when one of the notches 7 vor 72t is reached the spring l1 forces the hand into said notch and it then makes contact with the ring, and continues in contact until vagain lifted by the inclined tace ot' the next cam. This results in giving the minute hand an intermittent contact, and results in intermittent rines. The hands 2 andB are electrically connected together by means of a spring l2 which is secured to the hour hand and which is curved upwardly and inwardly'and bears upon the l under side ot the minute hand adjacent the minute hand arbor. This avoids the necessity of using the clock spring or mechanism for the purpose of forming a part of an electric circuit. v

In connection with the clock above deibed, employ a casing 13 which is divided into upper and lower portions. In the upper-portion of the casing twelve metal are arranged horizontally u on the inner face of the front oi:L the easing i '55 horizontal row ot buttons nre given numbers Q1 @einen und arranged vertically in the casing some fore, for exemple, u guest occupying room 1 distance back of and at right-angle?, t() the 1S t0 be Called nii 1G11 liilnufs after 51K, the
